HTML code is upside down

Occasionally, the code I paste into the inspector displays upside down. It’s very difficult to read this way. It does that for a while, then randomly I will launch RW, and it’s back to normal. But it doesn’t always self-correct with a restart. Anyone know why this would be happening and what I can do to make it show up correctly all the time?
